CHEVROLET Complaints

Vehicle would not shift through gears while driving. Torque converter shudder. Dealer found excessive metal in trans pan. Had to replace transmission. Vehicle had 107, 000 miles. Almost $5700 to replace transmission.

First started around 4 to 6000 miles, felt a shuttering between 50 and 65 mph. Shattering lasted from 10 to maybe 30 seconds let off the fuel and reapplied still there on one or two occasions. RPMs were approximately 2000 RPM shattering stopped in our PMs went down to 1500. This is occurred many times taken to a dealership always get same result, no problem found. Problem always occurs just after a transmission shift which I can tell by RPM. When I apply gas shuttering sometimes increases not always. Also noticed that sometimes shifting on a flat surface 65 miles an hour engine will speed up to almost 2000 RPM and when it goes to shift back, I get a clunk or sometimes a shutter normal cruising is about 1500 RPM at 65 mile an hour. I didn’t notice towing an empty trailer about 2600 pounds shattering seemed worse. With no Trailer I sometimes get erratic shifting where RPM goes 1500 to 2000 to 2500 and then back down again then back up again then it can shift all the way back to 1500 RPM still maintaining 65 mph. Also another problem may be connected to transmission, but I have pulled out into traffic pushed on the pedal and it feels like the truck has no power push on the pedal a little bit more still no power and all of a sudden it’s like everything kicks in RPMs, increase rapidly and truck accelerates extremely fast, throwing things off the dash moving things on the floorboard. Sometimes I see that a downshift occurs and RPMs increase other times I see RPM staying right at the 2000 mark and it still occurs almost got rear ended a couple of times. Check engine light has been on one dealership said they pulled over 40 codes. Still they all claim can’t duplicate problem. Yes I agree it is random but with me watching telemeter and County shift points biggest problem area is fourth gear fifth gear and sixth gear.

My trailblazer will not shift properly into drive from park or reverse. GM calls this a "loss of forward motion" or "delayed forward engagement" in their service bulletin TSB-24-NA-009. It is a safety issue because you never know when or how long the vehicle will take to engage and allow forward movement. This causes issues when leaving a parking spot or a driveway, especially on busy roads. If the car will not move forward, my family is stuck in the road until it finally engages into gear and allows forward movement. When this occurs, the vehicle engine will shutter and not allow any forward movement. I usually have to move the drive selector back to park and back to drive again. This creates an immediate and unreasonable safety risk because the vehicle will not move for several seconds while I am sitting in traffic. This generates a P2714 code. I had the car looked at by a GM dealer as well as an independent transmission repair shop and both indicate it will likely need a new transmission. GM is fully aware of the defect and has issued a service bulletin, TSB-24-NA-009 to instruct dealers how to diagnose and repair the problem. The bulletin proves a widespread engineering or manufacturing flaw exists. However, GM is treating this as a maintenance issue rather than the severe safety hazard that it is. It is my understanding, GM has since abandoned this transmission on the newer models, further indicating that GM knew these transmissions were not designed well. I am requesting the NHTSA office cross-reference my complaint with GM TSB-24-NA-009 and upgrade the component defect to a mandatory, manufacturer-funded safety recall before it causes a collision or fatal injury. Thank You

When driving, the vehicle’s computer detects an issue with the vehicle’s transmission and throws a “Reduced acceleration. Drive with care” which causes a strong jerk like if the wheel locked up momentarily. The check engine also turns on and the vehicle stays stuck in 5th gear at all times. Code P0747 is thrown as well.

I brought my Chevrolet Suburban High Country in to the dealer pursuant to a recall for engine issues due to a manufacturing defect in connecting rods and crankshafts that can cause catastrophic engine failure. The service center changed the oil viscosity and fill cap and stated that the change should eliminate the issue. I have had persistent engine knocking upon acceleration since then and it is getting louder and more prominent. A suspension warning intermittently flashes as well. Please advise, thank you

The vehicle's structural frame rails have suffered a catastrophic failure. The driver-side frame rail has a physical separation gap measuring between 1/2-inch and 1 inch wide. The passenger-side frame rail is actively delaminating and separating from the inside out. The vehicle and the failed component are completely intact and available for immediate inspection upon request. SAFETY RISK TO OTHERS:The structural integrity of the truck is entirely gone, creating an extreme safety hazard. If driven, the frame is at risk of snapping completely in half, which would cause an immediate, catastrophic loss of steering, suspension control, and braking on public roads, risking a fatal crash for the occupants and nearby drivers. CONFIRMATION BY A SERVICE CENTER:The problem has not been visually confirmed via a safety inspection. The catastrophic splitting aligns exactly with the premature corrosion patterns caused by the failing factory wax defect openly documented by General Motors in Technical Service Bulletin (TSB) 19-NA-255.4. INSPECTION BY MANUFACTURER/POLICE/INSURANCE:The vehicle has not yet been inspected by General Motors corporate, local police, or insurance representatives. It was immediately deemed unroadworthy and taken off public roads and parked. WARNING LAMPS AND PRIOR SYMPTOMS: There were no warning lamps, or dashboard messages. The only symptoms was when going over a bump it made a weird noises which was inspected and found the crumbling/failing frame. Because the multi-layered steel frame rots from the inside out due to moisture trapped behind the defective factory wax coating, the structural failure remained entirely invisible until the frame physically cracked open and separated.

My 10L1000 transmission had a catastrophic failure internally which caused it to rough shift, sudden down shifting, not want to shift into gear at all, and high engine rpm prior to roughly shifting. I took it to the Chevy dealers mechanic the very next business day, only to find out that from the mechanic that this is a common occurrence with Chevy transmissions in my truck and google also verified this to be a common problem. The mechanic from the Chevy dealership also stated that there was larger metal chunks than normal. My truck is available for inspection asap. The manufacturer and vin lookup contradicts the mechanic and google stating no issues or recalls for my transmission. After speaking with the manufacturer, I became highly concerned due to their unwillingness to address the obvious issues known by so many. If I wasn’t such a safe driver and immediately brought it to the mechanic, this could have caused a terrible accident leading to extreme bodily harm or death even. According to a quick google search of the 2021 Chevy 2500 transmission problems and my mechanic this is a well known problem even though Chevy manufacturers refuse to acknowledge the issue or implement a recall. There was zero warning lights or lamps to indicate this problem. I am extremely concerned with the manufacturer’s response to my concerns and their unwillingness to correct this issue before it cost someone their life. This catastrophic failure with the transmission having metal shavings throughout it and extreme damage to the transmission valve body and being well known and reported by many other customers has to be addressed. Chevy’s unwillingness to acknowledge people’s claims in this has left me with around $10,000 in monetary damages and could have lead to bodily harm or death if I would have been traveling on a main highway or interstate when it occurred. At the very least Chevy needs to be held responsible for this known and reported issue before it causes death or injury.

I am writing to log an official safety complaint regarding my 2023 Chevrolet Malibu. This vehicle is included under active NHTSA Campaign Number 26V212000 (GM Internal Recall Number N262551720) for a defective rearview camera housing that allows moisture intrusion, causing the backup display to go blank.My vehicle has experienced a complete, permanent failure of the rearview camera screen. The backup display is entirely black/blank when the vehicle is placed in reverse, eliminating all rear visibility. This creates an immediate, active safety hazard during everyday backing maneuvers and non-compliance with Federal Motor Vehicle Safety Standards.Despite the recall being announced months ago, General Motors has failed to provide a timely remedy or allocate replacement parts to my local dealership. Because my camera has actively failed, I am being forced to operate an unsafe vehicle indefinitely due to manufacturer parts delays. I request that the NHTSA investigate GM’s failure to supply remedy components to vehicle owners experiencing active component failures, as this delay leaves a known crash risk unresolved.

Radio does not emit sound also canceling all warning noises for fuel level, turn signals, seat belts, open door in motion. This problem is not only a saftey hazard for drivers its a major annoyance. Honestly find it quite distracting. Have reached out to gm multiple times and the issue hasn't been corrected. Really concerned this is going to plage my vehicle its whole life. This issue has happened more times than I can count.

The radiator had a crack that nobody located even though I had been smelling antifreeze since I purchased it at 24,000 miles just over a year ago. I brought it in for an oil change today because I was leaving town for the weekend tomorrow and now a hole had blown through the bottom of the radiator. Had this happened when I was in a remote area of the mountains without cell service this could have been a very big problem. Or had it blown while traveling up the mountain pass it would have put my life and others passing me on the road at risk. There weren't any warning lights on and the car never overheated. There weren't any outward leaks up until the hole was blown in the radiator. I have had it in several times for oil changes and there were never any visible leaks noted. Luckily my engine never blew because I've been driving with a cracked radiator for at least a year now.
